Using an iPhone or iPod Touch with an ELM327 Wifi OBD-II

With an application such as Rev for iPhone and a ELM327, you can wirelessly obtain a lot of information from your car. The App Store also has Rev Lite which lacks a lot of feature but can be useful to just test the connectivity before paying for a more expensive app.

Due to limitations in the iOS Bluetooth stack, make sure you buy the Wi-Fi version of it on eBay and not the Bluetooth one, unless you have jailbroken your phone and really know what you’re doing.

ELM327 can be ordered on eBay, most of them ship directly from Asia and should cost under $50 with shipping.

  1. Connect the ELM327 to your car.
  2. On your iOS device, in the Settings, chose to connect to a Wi-Fi network. My ELM327 is called “CLKDevices” but your mileage may vary. It should be relatively easy to find out which one it is unless you’re in a very Wi-Fi heavy area, in which case you can just drive a bit down the road and see what name hasn’t disappeared.
  3. Once connected to that Wi-Fi network, click the small blue arrow to go to the advanced settings for it. Set the IP Address to Static. Configure the IP address to and the Subnet Mask to Then, go back and exit the settings. Other guides/videos might tell you to configure an IP as a “router”. That is not only useless but annoying as it would mean your iPhone would attempt to join the Internet through your ELM327 and any data would not come through as it’s connected to your car. Don’t set a router.
  4. Start your car. The OBD-II port was providing power to the ELM327 but in some cases you will not be able to retrieve any data from it if the car is not started.
  5. In your App, configure the connection to use a custom TCP connection with IP and TCP Port 35000.
  6. Enjoy reading all this information on your car better and cheaper than by using the crappy scanners they sell in stores.

  2. Hugo says:

    I bought the elm327 obdII device and i have a iphone 4 and i can’t find the device on my wifi list… what can i do?

    • Guillaume says:

      It seems the SSID is somewhat random.
      Turn on the car with the device plugged, scan for networks (use a laptop, it’s a bit easier to refresh often). Note the list of SSIDs, then unplug the device and see if any network disappears.

      It could also be defective.

    • Kyle says:

      Have you found out the problem for not being able to find the obd device on wifi?
      I’m experiencing the same problem.

      • Spazticus says:

        I got mine to work, but I’m using iOS7.1.1 on a 4S. When I bought I my ELM327 I couldn’t get it to connect with anything, but I was using freebie software on an ancient laptop and an older iPhone (practically obsolete hardware to be honest). On a lark I downloaded the app and used the instructions above, and it connects nicely. I would note that, after plugging it in and turning on the vehicle, it seems to take mine about a minute before phone notices it. Once I added the IP address and Subnet Mask settings as described, all was good in the world.

      • Gabriel Rebelo says:

        Same thing here. Iphone 4, IOS 7 the wifi from the ELM just desapears….

    • dave says:

      I was just looking at a cheap one on ebay and go look at the fine print because it says it only works on the Android system some of them so play close attention to that first time ever on the site and maybe last but Casino pop up and thought I’d answer it…!!!

  3. Sam says:

    Which app are you using?

    I’ve tried using Rev Lite with the method you suggest above and it does not connect at all within the app.

    Connection to the ELM327 seems to be fine though – Clearly shows as connected.

    • Guillaume says:

      I had it working with Rev Lite, but now I use the full Rev.
      I think part of the problem is sometimes that these things are completely randomly setup. Some have different SSIDs, and maybe some even have different IP addresses.

      What I would suggest doing is: Connect your laptop to the ELM327 over wifi. Use a sniffer like Wireshark to see the traffic and determine the IP address of your dongle. That could be the issue.

      Also, using a Telnet client (such as Putty or even the built-in Windows telnet client – which isn’t installed by default on the latest versions), you should be able to telnet into the IP address of your ELM327 on port 35000 and see raw OBDII data. If not, you don’t have the right IP, it’s on a different port, or it’s another completely random thing.

      QA on these doesn’t seem to be a priority! Fortunately they are cheap..

      Another suggestion: Make sure you turn on the car before trying, simply plugging it in or setting the car to accessory will enable Wifi but not full connectivity.

    hello… either using rev lite or rev full version Iam unable to see boost and many many other options…. EML 327 wifi connected to OBDII on an Audi TT 2000

  5. Esteban says:

    Thank you Guillaume,

    Yes I see some useless data…not even rpms

    But tried DashCommand app and I am able to see rpms but not boost there for you right there are several PIDs not supported

  6. Larry says:

    Thank you very much this information is great. I have an additional question please.
    Assuming x2 applications on the iPhone both want to connect to the WiFi OBD ELM327 at the same time, is this possible and if so how would one accomplish this?
    Thanks in advance

  7. Kirill says:

    Hi! I’ve bought on of these ELM327 as well and mine works just fine with iPhone, but I can’t connect my Windows PC to the network. It just says “Windows was unable to join CLKDevices”. And a picture near CLKDevices in the list of available networks is three computers and a yellow exclamation mark. Have you tried to connect yours to a PC?

    • Guillaume says:

      I connected it to my Mac and it worked. Ensure you’re setting a static IP to your machine when on wifi..

      • Kirill says:

        Did you use MacOS on your Mac at that time or Windows? I’ve just tried MacOS and it also worked. But not Windows. Do you know of any good soft for MacOS? I only have ScanXL for Windows, but nothing for MacOS.

        • Guillaume says:

          I telnetted directly on Mac, it was just for troubleshooting.

          On Windows, if you connect and do ipconfig /all what is the output?

          • Kirill says:

            On windows I configure the adaptor (IP and Mask), then choose the CLKDevices network from the list and click Connect and then I get “Windows was unable to join CLKDevices”.

  8. felip says:

    iHi! I’ve bought on of these ELM327 as well but for some reason i cant connect with my iPhone5
    please help any body

    • Guillaume says:

      Provide more info. Do you see the wifi network at all? Is the problem wireless connectivity or getting apps to communicate?

      • Yana says:

        I have the same problem. I`ve read, that this is a problem of OBD interfaces. They say, that iphone 5 doesn`t support some features that is need to connect to OBD. So what should I do? To find and buy a new OBD or to wait for your software update?

        • Guillaume says:

          Just to be clear I don’t make any software. I’ll try it on my iPhone 5 probably tomorrow to see if it still works on the latest iOS and everything..

  9. tim ploeg says:

    I picked up an elm327 wifi and can connect to it from my IPhone 4. I can see the wifi connection but I too can’t get an app to connect to it. Using rev light i get an error saying device disconnected ( turn car off then on, unplug elm then replug) I have tried this and nothing works. I was able to use the demo software on the disk that came with it through my PC … but I want to use my phone. Please help

    • Guillaume says:

      Did you configure your laptop and iPhone with the same static IP for the wifi?

      Does the wifi connection establish properly from your iPhone 4?

  10. Arnaldo Lourencani says:

    I have a ELM 327 Wifi, can you send me the software for Iphone 4S ? I do no found it…
    Mey email is [email protected] from Brazil.
    Thanks in advance

  11. Nice. The custom IP setup was the key for me.

    As a reference for others, My SSID is WIFIODB2 on my ELM 327 (maybe someone googling it can find this page).

    I guess we both got a “good deal”: you gave me the answer I was looking for, I’m one of the developers for the Jetpack plugin (and WordPress[.com]) I notice your site is running. Enjoy, and thanks again for posting that! 🙂

  12. Ibrahim Khudrew says:

    Hi all,
    I have the ELM327 running on my iPhone 4S using the full version of Rev.
    My issue is it works very well one my main car however when connecting it to any other car does not work.
    It simply will not connect to the app. Any help with this issue would be greatly appreciated.
    Any suggestions would be greatly appreciated.

    Thanks! I just saved my husband from throwing his ipad across the garage!

    yeah, the elm327 is cheap and work great.

  15. Rocco says:

    Hi! I’ve connect my obd elm wifi to MY car (Bmw 2009) and works great with dashboard commander, when i try to use full Rev, Rev connects properly with elm (green light) and reads the VIN, but ALL pids shows the same blocked value! For example: rpm always 33, boost always 33 psi, speed always 33 mph…
    Do you have any ideas to resolve it??

    THANK YOU!!!

  16. PoPPaP says:

    Just wondering when connected to the ELM over wifi, can you still access the Internet through the cellular connection? Or would it timeout when trying to connect.

  17. PaulV says:

    Hi Gillaume… thanks for your info… got my Elm327 connected to my 4S in my MINI in flash.
    Just out of interest… the website blurb says… “It also includes a power switch built-in to prevent the need for having to constantly disconnect your unit from the OBDII port.”. Either its in software or I really am blind. The Elm looks just like the PLX’s but I noticed they have a tiny switch on the ‘wire’ end of the box… not my ELM327. Is that part of the cost-saving? Is it in software (is there an inactivity timeout?).

    • Guillaume says:

      I do not see any switch on mine.
      I would not leave it connected permanently in my car, I would be afraid of using too much of the car’s battery if I didn’t use it for a few days in a row.

      Also I left mine in for a while once and the wifi seemed to say active. I am not sure they have any inactivity timeout (at least mine – these things aren’t exactly all standard).

    • Steve says:

      I also read that there was an ON/OFF switch but my unit doe not have one either. I was disappointed that it does not. I’m sure someone here can figure out how to install one though.

  18. saad says:

    You change the settings by
    After rebooting the machine work
    Did not show me the name of the device?

    how i can rest?

  19. Guillaume says:

    I can confirm that this still works with the latest version of iOS (6.xx) on an iPhone 5.
    However, if you are unable to set the static IP (it always goes back to dynamic), try forgetting the network, turning off your phone and set the static IP after rebooting it.

  20. Manish says:

    Few questions:
    1. Does anyone have it working with a Mercedes?
    2. Any suggestions of apps besides Rev or DashCommand? Does anyone have it working with Engine Link?
    3. What are the potential apps that one can use on MacOS?


    • Steve says:

      I just got mine working with EngineLink (see my post below). Don’t have a Mercedes though. I’ve run it on my 02 Park Avenue and 99 F150 Triton.

  21. Steve says:

    The instruction here conflicts with the setup instructions that came with my ELM327 unit. My instructions say to set the IP address of the iPad and the ELM unit to the same address of The instructions in this blog indicate the IPs should be different which makes sense from a network point of view. You will not be able to get app (EngineLink in my case) to connect to your ELM with both IPs the same.

    My only question is regarding temperature. Is it normal for the ELM327 unit to become extremely warm during use? Mine becomes nearly too warm to handle and causes the dash above it to get extremely warm also, to the point I fear to leave it on for an extended period. For instance, if I wanted to let it run while driving on an extended trip of a few hours.

    • Guillaume says:

      Depending on who you bought it from, the instructions can be different as it’s a product sold to resellers who package it.

      Indeed, the IPs must be different.
      I’ve heard some people have devices with completely different IPs too. In my case, the IP wasn’t even in the instructions and I had to sniff and scan the network.

      Mine becomes very warm fast too. I would not leave it unattended and plugged in. I did drive with it for up to an hour with no issues but it’s definitely hot to the touch faster than that. Not the highest quality of a product I have seen but it’s good for pulling codes at least…

  22. Martin says:

    Hi I’ve just bought an ELM327 to read the fault codes on my ’05 ford focus, I’m having trouble connecting to either dashcommand or rev2lite,
    I’m using an ipad3 ios6 and my iphone5 ios6 and neither will work, I’ve been through the advice you gave earlier and changed the static ip on my phone to the one suggested, and set the ip in rev to the custom and entered the other ip, I can’t see anything happening in rev and dashcommand pops up with no device connected.

    I can connect to the network “clkdevice” but the softwares won’t connect. Any help please?

    • Martin says:

      I’ve just downloaded engine link and that worked first time, looks like its designed to work with the elm 327, shame the dealer I bought it from didn’t list it on his software list.
      Never mind, engine link has a step by step set up which is easy to follow and works,

      Now I just need to fix the car,

      Thanks everyone. Martin.

  23. Kalli says:

    I still can not connect to the iPhone 4S.
    All settings are as shown in the manual.

    When I type in Dashcmd with OPD II data port finder he find not the adapter.

    But when I type custom IP port 35000 and it can not open the data port.
    What is my mistake?
    Thank you

  24. Janson says:

    I have Iphone 4s and elm327 connected to a 2004 Ford Transit 2.0 tdci.
    The phone connected automatically to wifi called OBDII. I’ve tried the Rev2 Lite, and only reading I get is the voltage of the car battery. So there is a connection. Should the Lite version show more data than this? I only get the “metric is offline” notice.
    Or if this is a car make/model-based issue, I won’t spend my money on the full version.

    • Dan says:

      Brett, thanks for your post. I had iPhone 5s/ELM327 and it was connecting to wifi but failing to get any connection in DashCommand. I had the same static IP settings, but did not include any port.

      I got it working removing the IP from the “router” block, and setting up a “proxy server” identifying as the IP and 35000 as the port. Is that where you put the port or am I missing something else? Since it’s working now I don’t want to mess with it!

  38. Nelson L says:

    I can connect, no problems. But my car has no lights or warnings, and right after I connect it shows a couple of warnings for the traction control and transmission. Clearing them is pain, you do it using DashCommand, and they do not clear right away. You have to turn off the car and leave it off for a while and then it clears. But the Engine Light is on and only clears after two or three restarts. Is this common behavior to have after connecting? My car is a Chevrolet Captiva Sport 2.4l.

    • Nelson L says:

      Just to clarify, what I mean is: no codes before connecting the dongle, messages appear after I connect the dongle, and it is a pain to clear them. Is that normal?

  41. keith says:

    i logged into the admin for the device, changed the ssid, enabled a wifi password, then enabled low power mode. i did not see a reboot button in the admin area, so i pulled the elm327 from the car and put it back in. after it came back on it showed the new ssid but without a lock icon indicating no security. i cannot join thr wireless network anymore. not on ipad2/droid4/windows laptop and my macbook. before i made this changes it worked fine for the first 24 hours. my device came with dhcp enabled, i have tried using static ip settings in all devices and still cannot commect to the elm327’s wifi network. i think the only way to fix this is to reset it back to factory settings.. that would require jumping some pins i assume

    • Guillaume says:

      I have no idea how to reset it. Based on your experience, I would recommend people do not enable any kind of WiFi security on this thing. Actually, due to the power consumption and how warm it can get, I would highly recommend not letting it plugged in all the time and just using it for brief periods of time. For me, the risk of someone spying on my OBD2 codes is low enough!

        • Peter57 says:

          Just a small point: some cars (such as BMW) can be stolen if the criminal gets access to your OBD2 connector. It seems that OBD2 contains unprotected information which can be used to clone a car key which will start the engine. Getting access to wired OBD2 means jamming the remote control (door left open) or breaking the window, but much easier if you provide wireless access to the OBD2. These Wifi OBD2 dongles should have strong encryption and authentication, but it seems they don’t work with even with elementary security settings. Wifi and Bluetooth, strong avoid! Use wired only.

          • Guillaume says:

            Peter, this dongle is meant to be plugged to do troubleshooting – not to be left there. You are definitely right that an always on OBD2 wifi or Bluetooth connection would need to be secured properly. I’m quite certain the BMW connector uses some other protocols for advanced features like the ones used to clone keys.

      Did you figure this out? I have a similar problem. I can see the wifi on my phone but not connect with the app. Since only the red light(s) are blinking on the device I feel that there is a basic problem that I needs to be solved before trying to debug the connection to the app. Do you have a manual that tells that the different lights means? I got no manual so not sure what two blinkin red leds means…

    I bought one the ELM327 units online plugged it in and used a free app on my iPhone 6. It worked great! Took it out and plugged it in a couple hours later and it worked great again! Plugged it in about an hour ago and it connects and gives me one reading (can’t remember what it was) and nothing else. No speed. No rpm. No coolant temperature. All of these things it did give me the first two times I tried it. And advice would be greatly appreciated.

    Anyone got a manual for the CLKDevices? The manual I got with the purchase only shows how to setup the wifi and how to use the applications. However, I got two (out of five) leds that is blinking red and no manual to tell me what the leds means.

    Hope it’s not seen as spamming, but as some comments suggest terminal programs to check connections… Just thought I’d mention OBD Terminal for wifi elm327 devices on the iPhone and iPad App Store. It allows protocol selecting, and basic OBD commands to diagnose connection problems.

    There are some faulty OBD2 WiFi modules being sold on eBay.
    I had a couple of them myself and fixed them as described in this link:
